Abstract: Described herein are methods of forming a VOC and odor-reducing building panel. The methods include providing a substrate; applying a wet-state coating to a major surface of the substrate, the wet-state coating comprising carrier comprising water; and drying the wet-state coating, thereby evaporating at least 95 wt. % of the carrier to form a dry-state coating.

Abstract: Described herein is an stain and sag resistant acoustic ceiling panel comprising a porous body formed from mineral and cellulosic fibers having an upper surface opposite a lower surface and at least one side surface extending between the upper surface and the lower surface; a first layer applied to the upper surface, the first layer comprising a hygroscopic component and a hydrophobic component; and a second layer applied to the lower surface, the second layer comprising a hydrophobic component.
